Abstract
AC motor in life are widely used, and has the advantages of simple operation, is currently the AC power transmission is the main motive power, AC motor starting method has many kinds, starting manner to the motor is very important, the traditional start way interleaving is simple, but there are many drawbacks. The current frequency conversion and development of soft starter technology, can fundamentally solve the traditional starting problems, especially the soft starting technology in solving large, medium capacity motor startup problems in a excellent performance, can be said to be instead of the traditional starting mode, especially the step-down starting a new technology.
Key words: AC motor soft start; start;
